DETAILED DESCRIPTION

Exercise devices and systems that can be mounted to a door frame and that can be used to work out a variety of different muscle groups are provided herein. For example, the exercise devices and systems provided herein can be used to perform exercises that involve abdominal, core, and tricep muscle groups.

FIG. 1 illustrates an exercise device 100 according to the present invention. Exercise device 100 may be suspended from a door frame mountable device, such as a pull-up bar. Exercise device 100 enables a user to perform a number of different exercises using the weight of the user's own body and gravity as resistance.

As shown in FIG. 1, exercise device 100 includes a body engaging structure 110, a stabilizing member 140, and a connecting structure 150. Body engaging structure 110 includes a right forearm engaging member 112 and a left forearm engaging member 114. When exercise device 100 is suspended from a door frame mountable device, right and left forearm engaging members 112 and 114 may be positioned in a generally horizontal orientation and may provide a user with a place to rest his or her forearms during the performance of an abdominal exercise on exercise device 100. FIG. 3C illustrates exercise device 100 being used to perform an abdominal exercise (e.g., a vertical knee raise exercise). Given that most or all of a user's weight may be placed on his or her forearms during the performance of an abdominal exercise, right and left forearm engaging members 112 and 114 may include a right cushioning member 116 and a left cushioning member 118, respectively.

To provide additional stability to a user performing an exercise on exercise device 100, right and left forearm engaging members 112 and 114 may also include a right stabilizing handle 120 and a left stabilizing handle 122. Right and left stabilizing handles 120 and 122 may extend away from right and left forearm engaging members 112 and 114, respectively, at generally right angles such that a user may easily grasp handles 120 and 122 when the user's forearms are positioned on right cushioning member 116 and left cushioning member 118. A user may grasp right and left stabilizing handles 120 and 122 to avoid the user's forearms from unintentionally slipping off of right forearm engaging member 112 or left forearm engaging member 114 during the performance of an abdominal exercise on exercise device 100.

Right and left forearm engaging members 112 and 114 may further include a right dip handle 124 and a left dip handle 126. Dip handles 124 and 126 may be grasped by a user performing dip exercises on exercise device 100. FIG. 2C illustrates exercise device 100 being used to perform a dip exercise. When exercise device 100 is suspended from a door frame mountable device, dip handles 124 and 126 may be positioned in a generally horizontal orientation.

The outer surfaces of right and left stabilizing handles 120 and 122 and right and left dip handles 124 and 126 may be covered in part or in whole in a material that helps to prevent a user's hands from slipping during performance of an exercise. For example, handles 120, 122, 124, and 126 may include an outer covering made of foam, rubber, or another material that helps to prevent slipping.

Body engaging structure 110 may also include a back engaging member 128. When exercise device 100 is suspended from a door frame mountable device, back engaging member 128 may be positioned in a generally vertical orientation and may provide a user with a place to position his or her back during the during the performance of an abdominal exercise on exercise device 100. For added comfort, back engaging member 128 may include a cushioning member 130.

Right and left forearm engaging members 112 and 114 and back engaging member 128 may be secured together via a direct or an indirect connection. For example, with regard to exercise device 100, right and left forearm engaging members 112 and 114 and back engaging member 128 are each directly connected to stabilizing member 140 and thus indirectly connected to each other.

In addition to connecting right and left forearm engaging members 112 and 114 and back engaging member 128 together, stabilizing member 140 may be configured so that it contacts a wall to either the right side or the left side of a doorway in which exercise device 100 is to be used. The term “wall” as used herein broadly includes any material that may be used as a vertical partition, including but not limited to wood (e.g., a wooden door frame that defines a doorway), sheet rock, plaster, cement, brick, stone, or another material. This wall contact may provide stability to exercise device 100 during the performance of an exercise.

As shown in FIGS. 2B, 3B, and 3C, stabilizing member 140 may also be longer than the width of a doorway such that contact is made with the wall both on the right side and on the left side of the doorway, thus providing an added amount of stabilization for exercise device 100. Stabilizing member 140 may include pads 142 a and 142 b in the places where contact may be made with a wall. These pads may help avoid marring or otherwise damaging walls and may further ensure a stable connection. Pads 142 a and 142 b may be made of foam, rubber, or another material.

Exercise device 100 also includes a connecting structure 150. Connecting structure 150 connects body engaging structure 110 and stabilizing member 140 with a mounting structure. A mounting structure, according to the present invention, may take on any number of different forms. FIGS. 2A and 3A illustrate two different example mounting structures 170 and 190, which will be discussed in greater detail below.

As shown in FIG. 1, connecting structure 150 comprises a right elongated member 152 and a left elongated member 154. Right elongated member 152 and left elongated member 154 may be generally parallel and may further be positioned in generally vertical orientations. Right elongated member 152 and left elongated member 154 may be connected to body engaging structure 110 and/or stabilizing member 140 through either direct or indirect connections. These connections may be permanent. For example, to the extent that both body engaging structure 110 and connecting structure 150 are made from a metal based material, these components may be permanently welded together. In addition, connecting structure 150 may be integrally formed with body engaging structure 110 and/or stabilizing member 140. Alternatively, the connection between connecting structure 150 and body engaging structure 110 or stabilizing member 140 may be selectively releasable such that connecting structure 150 may be selectively disconnected from body engaging structure 110 and/or stabilizing member 140.

The length of right and left elongated members 152 and 154 may be selectively adjustable. One of skill in the art will appreciate that there are many different mechanisms that may allow the length of right and left elongated members 152 and 154 to be selectively adjustable. For example, right and left elongated members 152 and 154 may include right and left telescoping mechanisms 156 and 158, respectively. Telescoping mechanisms 156 and 158 may allow an upper portion of elongated members 152 and 154 to fit within or about a lower portion of the elongated member. Right and left telescoping pins 160 a and 160 b may fit within holes 162 a and 162 b to secure telescoping mechanisms 156 and 158 in a configuration so that right and left elongated members 152 and 154 are at a desired length.

Right elongated member 152 and left elongated member 154 also include attachment mechanisms 164 and 166, respectively. Attachment mechanisms 164 and 168 may be connected to a mounting structure. A mounting structure may be any structure that is securable to a door frame and that is capable of suspending exercise device 100. As discussed in more detail hereafter, FIGS. 2A and 3A illustrate perspective views of example mounting structures 170 and 190.

Right and left attachment mechanisms 164 and 166 may include right and left generally inverted u-shaped members 168 a and 168 b that hook to a generally horizontal portion of a mounting structure. Right and left attachment mechanisms 164 and 166 may further include right and left attachment pins 169 a and 169 b, which can extend between two ends of u-shaped members 168 a and 168 b to lock a generally horizontal portion of a mounting structure within u-shaped members 168 a and 168 b.

Referring to FIG. 2A, mounting structure 170 includes a first cross member 172, a second cross member 174 and mounting members 176 and 178. First and second cross members 172 and 174 may have lengths that are more or less than the width of a doorway. Mounting members 176 and 178 are generally L-shaped and include generally vertical portions 180 a and 180 b, respectively, and generally horizontal portions 182 a and 182 b, respectively. First cross member 172 is connected to generally vertical portions 180 a and 180 b of mounting members 176 and 178. Second cross member 174 is connected to generally horizontal portions 182 a and 182 b of mounting members 176 and 178. As a result, first and second cross members 172 and 174 are both horizontally and vertically offset from one another.

FIG. 2B illustrates a front view of a door frame 188 and depicts how exercise device 100 may be suspended from door frame 188. Specifically, FIG. 2B illustrates an exercise system that includes exercise device 100 and mounting structure 170. Mounting structure 170 may be positioned on door frame 188 so that the first cross member 172 passes through the doorway defined by door frame 188 and contacts a first side of a wall above the doorway. As can be seen in FIG. 2B, first cross member 172 optionally has a length that is less than the width of the doorway.

Vertical portions 180 a and 180 b of mounting members 176 and 178 extend downward and horizontal portions 182 a and 182 b extend through the doorway so that second cross member 174 engages a second side of the wall. Second cross member 174 may engage the second side of the wall in a single or multiple places. With regard to mounting structure 170, second cross member 174 has a width that is greater than the width of the doorway such that it contacts the second side of the wall in two places: to the right of the doorway and to the left of the doorway. A downward force exerted on second cross member 174 causes first and second cross members 172 and 174 to be pressed against opposing sides of the doorway, thus holding mounting structure 170 securely in place.

Exercise device 100 can be selectively attached to mounting structure 170. For instance, right and left attachment mechanisms 164 and 168 may be positioned about second cross member 174 to selectively suspend exercise device 100 from door frame 188 as illustrated by the arrows in FIG. 2B.

FIG. 2C illustrates a side view of exercise device 100 mounted to door frame 188 via mounting structure 170 and depicts how exercise device 100 may be used to perform dip exercises. As depicted in FIG. 2C, a user 189 may grasp dip handles 124 and 126 and raise and lower his or her body with his or her feet off the ground. User 189 may face either toward or away from exercise device 100.

FIG. 3A illustrates another example mounting structure 190. Mounting structure 190 includes a right inner door frame mount 192, a left inner door frame mount 194, and a bar 196. Right and left inner door frame mounts 192 and 194 may be secured to opposing inner vertical portions of a door frame. Right and left inner door frame mounts 192 and 194 may further include brackets that allow bar 196 to be secured between right and left inner door frame mounts 192 and 194. The length of bar 196 may be selectively adjustable to ensure that bar 196 will fit within a doorway.

FIG. 3B illustrates a front view of a door frame 198 and depicts how exercise device 100 may be suspended from door frame 198. Specifically, FIG. 3B illustrates an exercise system that includes exercise device 100 and mounting structure 190. Right and left inner door frame mounts 192 and 194 of mounting structure 190 are secured to right and left inner vertical surfaces, respectively, of door frame 198. Exercise device 100 can be selectively attached to mounting structure 190. Specifically, right and left attachment mechanisms 164 and 168 may be positioned about bar 196 to selectively suspend exercise device 100 from door frame 198 as illustrated by the arrows in FIG. 3B.

FIG. 3C illustrates a front view of exercise device 100 mounted to door frame 198 via mounting structure 190 and depicts how exercise device 100 may be used to perform abdominal exercises. As depicted in FIG. 3C, a user 199 may rest his or her forearms on right and left cushioning members 116 and 118, grasp right and left stabilizing handles 120 and 122 and raise and lower his or her knees.

FIG. 4 illustrates an exercise device 200 according to another embodiment of the present invention. Exercise device 200 includes a body engaging structure 210 and a connecting structure 250. Body engaging structure 210 and connecting structure 250 each perform functions and include components that are similar to exercise device 100. For example, body engaging structure 210 includes right and left forearm engaging members 212 and 214 and a back engaging member 215. Body engaging structure 210 also includes a right forearm engaging member 216, a left forearm engaging member 218, a right stabilizing handle 220, a left stabilizing handle 222, a right dip handle 224, and a left dip handle 226.

Connecting structure 250 includes a right elongated member 252 and a left elongated member 254. Right and left elongated members 252 and 254 are connected to body engaging structure 210, and may be formed integrally therewith. Connecting structure 250 also includes an attachment mechanism 256 and a stabilizing member 240. Unlike exercise device 100, however, stabilizing member 240 does not engage any portion of a wall surrounding a doorway. Also unlike exercise device 100, attachment mechanism 256 in exercise device 200 is itself a mounting structure. Thus, exercise device 200 does not secure to and suspend from a separate mounting structure. Rather the mounting structure is part of connecting structure 250 in exercise device 200.

Attachment mechanism 256 includes a first cross member 272, a second cross member 274 and mounting members 276 and 278. First cross member 272 may have a length that is less than the width of a doorway. Second cross member 274 may have a length that is greater than the width of a doorway. Second cross member 274 may also include grip members 275 a and 275 b that may be used to perform pull-up or chin-up type exercises. Mounting members 276 and 278 may include generally vertical portions 280 a and 280 b, respectively, and generally horizontal portions 282 a and 282 b, respectively. First cross member 272 is connected to the generally vertical portions 280 a and 280 b of mounting members 276 and 278. Second cross member 274 is connected to the generally horizontal portions 282 a and 282 b of mounting members 276 and 278.

Attachment mechanism 256 may be positioned on a door frame so that the first cross member 272 passes through the doorway defined by the door frame and contacts a first side of a wall above the doorway. Vertical portions 280 a and 280 b of mounting members 276 and 278 extend downward and horizontal portions 282 a and 282 b extend through the doorway so that second cross member 274 selectively engages a second side of the wall. A downward force exerted on second cross member 274 causes first and second cross members 272 and 274 to be pressed against opposing sides of the doorway, thus holding exercise device 200 securely in place.

In exercise device 200, mounting member 276 is integrally formed with right elongated member 252 and right forearm engaging member 212. Mounting member 278 is integrally formed with left elongated member 254 and left forearm engaging member 214. Generally horizontal portions 282 a and 282 b are substantially parallel to one another. Right and left elongated member 252 and 254 are generally vertical and substantially parallel to one another. Stabilizing member 240, first cross member 272, and second cross member 274 are each generally horizontal and substantially parallel to one another.
